OPERATING INSTRUCTIONS Set the thermostat to either HEAT or COOL as desired. Set the desired temperature on your thermostat dial and set the fan switch to “ON” (for continuous air circulation) or to “AUTOMATIC” (for air circulation only when the air conditioning system is operating). If you desire to vary the thermostat temperature setting during the day for energy conservation (for example, while you are at work) do not vary the setting more than 5°F from your normal temperature setting. Changing the temperature more than 5°F or turning the thermostat off for periods less than 12 hours can actually cost you more in energy consumption than keeping the temperature constant. You should also consider indoor plants and pets when varying the temperature from the normal comfort level. IMPORTANT: Wait at least three (3) minutes after turning the heat pump off before trying to restart. If an attempt is made to start the compressor before the refrigerant pressures are equalized, the compressor motor may trip on its overload. An additional waiting period will be required before restarting. MAINTENANCE 1. Always install and keep filters clean. Check filters every 10 days to 2 weeks. Clean or replace if necessary. The factory-installed filter is located behind the center front access panel. ! TO CHANGE SYSTEM FILTER: A. Turn the power to the unit off at the unit disconnect. The disconnect is located on the front of the H Series unit behind a small access door. WARNING: SERIOUS INJURY MAY RESULT IF WATER SPRAY IS DIRECTED TOWARD LIVE ELECTRICAL CONNECTIONS OR POWER SOURCES. TO CLEAN FRESH AIR INTAKE FILTER: B. Remove the front center access door from the unit. A. Follow steps A and B at left “TO CHANGE SYSTEM FILTER”. C. Remove and replace the filters with the type and size indicated in the table below. B. Gently pull out the filter from the bottom. D. Replace the access door and turn on the power to the unit. INSULATION 2 1 CLOSED DAMPER DOOR C. Wash the filter with water. NOTE: If your system has a filter grille installed in the return air opening, the unit filter should have been discarded during installation. UNIT MODEL QTY.

Reinstall the filter, by sliding it into the retaining rail. SCREW FILTER E. Replace the access door and turn the power on to the unit. 2. Keep the outdoor coil clean. Wash it down with a garden hose if necessary. BE SURE THE UNIT DISCONNECT IS IN THE “OFF” POSITION AND THAT ALL ELECTRICAL POWER TO THE UNIT IS TURNED OFF BEFORE CLEANING THE SYSTEM. Remove any loose grass, leaves, papers, etc., from the area around the condenser coil. These could reduce the air supply through the coil and reduce the amount of cooling capacity. The filter installed into the return air grille assembly should be replaced with the same size and type provided with the grille. 3. Since the heat pump is located outdoors, it is exposed to all weather elements. Treat it with a good automobile paste wax twice a year (in the spring and fall). If your system is equipped with a fresh air intake, the filter for the fresh air assembly is accessed through the front center panel. The filter is a permanent washable type. Check with your contractor if you have any questions regarding the maintenance or operation of your unit. 3 INSTALLATION D. DUCTWORK A. CODES The installer SHALL comply with all local, state, and federal codes and/or regulations pertaining to this type of equipment and its installation. Such codes and/or regulations should take precedence over any recommendations contained herein in lieu of local codes. Installations SHALL be made in accordance with the National Electrical Code, local codes, and recommendations made by the National Board of Fire Underwriters. 1. Properly-sized duct systems are critical for satisfactory operation of any heat pump system. All ductwork MUST be correctly sized for the design air flow requirement of the equipment. B. UNIT SITE LOCATION 3. Ductwork routed through wall cavities, as well as any duct not in conditioned space, MUST be insulated. Supply ducting routed through exterior walls MUST be insulated with 1" insulation to the back of the unit. 2. The recommended operation duct static is to deduct 0.07" W.C. for any size of heater 5 kW to 20 kW on factory- or field-installed heaters. 1. To eliminate noise from being transmitted into noise-sensitive areas, the unit should NOT be installed on walls adjoining bedrooms, sleeping quarters, or adjacent to windows. 4. Supply and return air ducts should be flush with the exterior wall and sized to fit over the unit duct collars in order to compress the collar air gasket. 2. Locating the unit as close as possible to the main duct system or area to be conditioned, will prevent lengthy duct runs and unnecessary thermal and air-pressure losses. 5. If supply duct is flashed to the exterior of a building constructed with combustible material, the flashing MUST be insulated in order to maintain the required clearances to combustible materials. Required clearance is 1/4" for the first three (3) feet of supply duct. 3. The clearance to combustibles is 0" on all sides, and 1/4" for the first three (3) feet of supply duct. 4. The condenser air inlets (left, right and bottom inlets) SHALL be located at least 8" away from walls or other obstructions for unrestricted airflow. E. FILTERS 5. The condenser air outlet should be located at least 6’ away from any obstructions to prevent recirculation of condenser air. 1. One-inch disposable filters are supplied standard in each unit. Two-inch disposable filters can also be used and are available as an option. The filter rack is adjustable to accommodate 2 " filters. The filter rack on this series is adapted by bending the retaining brackets. Refer to the Maintenance section on page 3 for the procedures for changing the filters. 6. Service clearance is 28" from the electrical box access panel located on the front of the unit and 28" from the center, upper, and lower front access panels. 7. The wall selected for unit installation MUST be able to or be made to safely support the weight of the unit. 2. If a filter grille is used in the installation, the filter should be properly sized to allow a maximum velocity of 400 FPM. THE FACTORY-INSTALLED FILTER MUST BE REMOVED. 8. Do NOT locate where heat, lint or exhaust fumes will be discharged on the unit (as from dryer vents). C. UNIT PREPARATION F. ELECTRICAL POWER 1. The H Series model units have top rain flashing built onto the unit. The bottom-mounting flange for all models is shipped separately and in place. (Refer to “Section J. Unit Installation” for the recommended use of the bottom flange.) The installer MUST check available power to make certain it matches the unit nameplate rating and that constant voltage can be maintained to the unit. Unsatisfactory and unsafe performance could otherwise result. The local power company should be contacted about questions concerning power supply. 2. Electrical entrances are located on the right side, left side, and back of all H Series units. Refer to “Section H. Electrical Hook-up” for details. 3. Return and supply air collars and air gaskets are factory installed. G. BREAKER/DISCONNECT ASSEMBLY 4. The supply and return air ducts should be checked to be sure they: These units are standard equipped from the factory with a unit disconnect. This is in the form of a circuit breaker (230V models) or a disconnect (460V models). If an optional electric heat kit is to be installed, follow the instructions included with the heater assembly. See Figure 1 for reference. a. Match the openings on the unit to be installed. b. Have the same distance between them vertically as the openings on the unit to be installed. 5. If the factory-installed filter is used on your installation, access to the filter is made through the center panel on the front of the unit. IF A REMOTE FILTER IS USED, SUCH AS A FILTER GRILLE, THE FACTORY-INSTALLED FILTER MUST BE REMOVED AND DISCARDED. FIGURE 1 Electrical Box Breaker 4 Breaker Mount ! J. UNIT INSTALLATION WARNING: ELECTRICAL EQUIPMENT SHOULD BE INSTALLED BY A QUALIFIED, LICENSED ELECTRICIAN. IMPROPER ELECTRICAL HOOK-UP MAY DAMAGE EQUIPMENT, CAN CREATE A HAZARD, AND WILL VOID WARRANTY. H SERIES UNITS ARE FOR USE IN SINGLE-STORY BUILDINGS ONLY 1. As previously stated, the wall that the unit is to be installed onto MUST be strong enough to support the unit under the condition for which it will be used. For example, a unit to be installed on a building that is intended to be transported will require more wall strength than a unit installed at a permanent site. Existing walls may need additional reinforcement. NEVER RELY ON EXTERIOR SIDING OR PLYWOOD TO SUPPORT THE UNIT. Figure 2 below represents a typical installation of a single-story stud wall at a permanent site. Since building materials and techniques vary with regions and intended use, a building contractor and/or local building code official MUST be consulted for suitable construction methods. H. ELECTRICAL HOOK-UP The line voltage electrical service can be routed through the right side panel, the right side of the back panel, or left side panel. Each area is supplied with two line voltage knock-outs (1/2" – 3/4" and 1" – 11/4"). Low voltage wiring can be routed through the right side panel. NOTE: When routing line voltage through the return air compartment, conduit MUST be used (even though this is a dry area) to comply with the NEC code. A 11/4" PVC conduit is supplied for this application. Refer to the tables on pages 14 – 15 for minimum wire size and maximum breaker size. All wire sizes listed under the dualfeed circuit column are based on no more than three (3) conductors in the same conduit. If two circuits or more than three (3) conductors are to be routed in the same conduit, the ampacity of the wire size listed MUST be derated. Refer to Article 310 of the NEC code for adjustment factors. Be sure to install a ground wire of the proper size to the unit’s equipment ground lug. 2. Locate and attach the lower mounting bracket in the desired location on the building. 3. Apply a suitable caulk across the entire length of the top rain flashing and side mounting flanges. 4. Remove the flanges on both ends of the pallet and slide the unit approximately 2” off the rear of pallet. Lift unit gently into location with fork truck, taking care to align unit with lower mounting bracket. I. LOW VOLTAGE WIRING 5. While allowing a small portion of weight on the lower bracket, push the unit against the wall and fasten appropriately. 230 volt, 1- and 3-phase units are equipped with dual-primary voltage transformers for 208/240 volt operation. These models are factory wired to the 240 volt tap. For 208 volt operation, connect the factory-installed black wires from the 240 volt tap to the 208 volt tap. The acceptable voltage range of the tap is as follows: Tap Voltage Range 240 Volt 253 - 216 208 Volt 220 - 187 Seven (7) conductor thermostat wires should be run from the thermostat location to the unit. Thermostat wire should be sized as shown on the table below. FIGURE 2 Refer to wiring diagrams on pages 16 – 18 for connection details.

Units over 10 kW resistance heat also have an additional stage for emergency heat. The first stage is refrigerant heat (Y and G terminals are energized and O terminal is de-energized). The second stage is auxiliary resistance heat (W is energized). The third stage is emergency heat (E and W terminals are energized). H Series units are equipped with an emergency heat lock-out relay. This will disable the compressor when the E terminal is energized. Do not install a jumper between the W and E terminals. This would keep the compressor contacts from being energized and prevent the compressor from operating. K. CONDENSATE DRAIN A 3/4” drain hose is located on the bottom side of the unit. The drain may be extended for condensate removal to comply with local codes (use fitting size or larger). Install a condensate trap on this line. L. ELECTRICAL HEAT INSTALLATION Electric heat is an option on H Series units and can be field-installed on either single- or three-phase models. Refer to the individual installation instructions for installing heater kits. 5 DEFROST TIME SELECTION M. DEFROST CONTROL The defrost control has three selectable time intervals: 30, 60 and 80 minutes. The timing is factory set at 60 minutes. This timing has been determined by testing to provide the best operating efficiency. In areas where the humidity is lower than normal, the timer may be set to a higher time (80 minutes). To change the time, move the timer jumper to the post marked 30 for 30 minutes, 60 for 60 minutes, or 80 for 80 minutes. The H Series units use an integrated defrost control to manage the following control functions of the system: 1. Off and on functions of the outdoor fan during the defrost and heating mode. 2. Off and on functions of the reversing valve during the defrost and heating mode. 3. Off and on functions of the auxiliary heat relays during the defrost mode. DEFROST TEST POST The defrost control has test posts to speed up the defrost time setting by a factor of 256. The control is a time-and-temperature type with selectable defrost time intervals of 30, 60 and 80 minutes. Control circuit voltage at the control is 24 volts input and output. The outdoor fan relay is SPNC (single pole normally closed) and controls the fan motor. If you want to initiate a defrost without waiting for the time to accumulate, you can jumper the two test pins (marked test). If the coil temperature is above 30°F you will need to jumper the DFT (defrost thermostat) terminals to simulate a closed thermostat. The defrost cycle should occur in 7 seconds for a 30-minute setting, 14 seconds for a 60-minute setting, and 17 seconds for an 80-minute setting. If the jumper is removed immediately when the defrost cycle starts, the cycle will end if the defrost thermostat is opened (coil above 65°F). If the test pins remain jumped, and the defrost thermostat is closed, the defrost will end in 2.3 seconds, which is the 10-minute default. BASIC SEQUENCE OF OPERATION COOLING MODE Low-voltage thermostat terminal R is connected to Y and O, at the unit low-voltage terminal board. The system reversing valve is powered during the cooling mode. Power is supplied to the reversing valve solenoid through the lowvoltage O terminal. The low-voltage Y terminal to the control will energize the contactor latch coil (causing the contactor to energize the compressor). The low-voltage Y terminal to the control will also energize the control's timer. During the cooling mode, the defrost thermostat is open (coil temperature is above 30°F) and will not allow the time to be accumulated to initiate the defrost mode. The outdoor fan is wired through the N/C points of the control’s relay and the N/O points of the contactor. The fan motor will be energized whenever the contactor is energized (except during defrost). DURING THE ABOVE TEST, DO NOT CONTACT OR SHORT ANY OTHER PIN. THIS MAY DAMAGE THE CONTROL. FIELD CHARGING Compared to a cooling-only unit, a heat pump is difficult to field charge correctly without the use of charging scales. It is recommended the charge be weighed in with an accurate charging scale. The correct charge weight can be found on the unit name plate. HEATING MODE Low-voltage terminal R is connected to Y and G, at the unit lowvoltage terminal board. N. HIGH PRESSURE LOCK OUT The system reversing valve is not powered during the heating mode. With the thermostat system switch turned to heat, the low-voltage O terminal is now disconnected, turning the reversing valve solenoid off (switching the reversing valve to the heat position). The Y terminal will energize the contactor and outdoor fan and the G terminal will energize the indoor blower. H Series units are equipped with a high pressure switch. This switch is wired through a lockout relay to lock out the system if the high side pressure exceeds 425 psi. If the system is locked out by the pressure switch, it can be reset by cycling the indoor thermostat off and back on. The high side pressure MUST be below 300 psi before the system can be reset. DEFROST MODE To prevent heavy ice build-up on the coil during the heating mode, as the outdoor coil temperature falls below 30°F ± 5°F, an outdoor defrost thermostat closes. (This thermostat is located on a coil tube.) When the thermostat closes, the timer on the defrost control starts accumulating the compressor run time. After the selected time (30, 60, or 80 minutes) has been accumulated, the controller will start the defrost cycle regardless of the outside temperature. During the defrost cycle, the system is switched back into the cooling mode by the control energizing the reversing valve solenoid. The N/C pole of the control fan relay is opened, turning off the outdoor fan to allow the outdoor coil to be warmed (defrosted) faster. The defrost control energizes the indoor auxiliary heat relays through the W2 terminal to temper the indoor supply air. This terminal should be connected to W2 (second-stage heat) on the thermostat.
